Ready to rock your boat

Rockford Fosgate designed their Power Series TM400X2ad 2-channel amplifier for marine and powersports applications. This rugged, marine-rated amp puts out some serious power, great news if you're big on bass.

Rockford Fosgate's proprietary Class AD technology allows this compact amp to draw big power with less current draw from your electrical system, while the Constant Power feature keeps power consistent with varying impedances. High- and low-pass filters tailor the amp to the job at hand, whether it's powering a nice set of component speakers or a couple of marine subs.This amp will provide outstanding power and versatility in a variety of vehicles on land and sea.

Made to handle moisture and heat

It's built to stand up to outdoor life, too, with conformal-coated circuitry that withstands moisture and dirt and stainless steel hardware that won't succumb to corrosion. With a 3-stage thermal lock extrusion, dual- fan forced induction system, and real-time thermal monitoring, this amp can rock hard without overheating – even when it's tucked into a tight space.

Level setting made easy

The TM400X2ad uses Rockford Fosgate's CLEAN level setting technology, so there's no more guesswork while setting your gain levels. Easy-to-see LED indicators identify clipping so you can set your amp up for maximum performance while eliminating distortion.

Rockford Fosgate TM400X2AD

They really rocks, has great power I purchased two of them for my motorcycle. I have eight speakers, saddle bag with four 6x9 Polk speakers and four 5.25 speakers in canisters. They sounds awesome, ran in stereo at 2omh, you will enjoy the clean sound music. I am very happy with my purchase.

Rockford Fosgate TM400X2AD

This amp fit my application perfectly. It is compact, easy to install and wire, easy to tune, and has plenty of power. The QC test certificate that comes with it has it rated at 50 WRMS higher than advertised.

Product Research

Features

Overview: The Rockford Fosgate TM400X2ad is a 2-channel
Power Series moto-marine amplifier with a rated power output of 200 watts per channel
at 4-ohms or 2-ohms. This Element Ready amplifier can be used on motorcycles,
ATVs, or boats, and can withstand harsh environmental conditions.

CEA-2006 Compliant: CEA-2006 is a system of testing and
measurement methods for mobile audio amplifiers. This voluntary standard
advocates a uniform method for determining an amplifier's RMS power output and
signal-to-noise ratio. The criteria for measuring power uses a DC input voltage
of 14.4 volts and the RMS power output is measured into a 4Ω load with 1%
or less Total Harmonic Distortion plus noise (THD+N). CEA-2006 allows consumers
to compare amplifiers and receivers under identical conditions. The CEA-2006-rated
RMS power output is 200 watts RMS x 2 channels. Additionally the power output is
200 watts RMS x 2 channels
into 2Ω and 400 watts RMS x 1 channel bridged (into 4Ω).

Element Ready: Rockford Fosgate's Element Ready Amplifiers
are protected against dust, UV rays, and corrosion. Marine-grade, two-part
epoxy-coated circuit boards are used to prevent corrosion due to exposure in
moist and humid places. In addition, stainless hardware is used to help prevent
rust and corrosion of all electrical connections.

Class-AD: The TM400X2ad features Rockford Fosgate's
proprietary Class-AD technology, which allows the amplifier to produce more
power with less current draw from the vehicle's charging system.

3-Stage Airflow: The amp's 3-stage airflow method
efficiently rids the chassis of heat to keep the amplifier running cool. Dual
fan forced induction pulls in fresh air. The air flows over the MOSFET
transistors to cool them down, and out through the exhaust channel. The top and
bottom heat sinks are decoupled, which allows the top to remain cool to the
touch. At least 2-3 inches clearance should be provided around the fan intake
and the exhaust vents to optimize air flow.

DSM (Discrete Surface Mount): High speed robotics are used in the
manufacturing process to place 1% tolerance parts and large board traces. DSM improves
the efficiency of the circuit, decreases cross-talk from other discrete components and
lowers operating temperature.

CLEAN Set-Up: Rockford's integrated level setting technology, CLEAN
(Calibrated Level Eliminates Audible Noise), replaces sophisticated test equipment with
input/output clip LEDs, allowing you to match the source unit's output to the amp's gain,
and optimize the amp's output. The input clip indicator works in conjunction with the
audio source volume, illuminating red when the source reaches its clipping point. The
output clip indicator works in conjunction with the input level dial on the amp,
illuminating the appropriate color depending on the audio content used for the
setup.

Controls

Input Level: The amplifier has a single input level control,
conveniently accessible from the top. To accommodate the varying range of
signal levels from today's factory and aftermarket radios, the input levels are
adjustable from 150mV to 12V. A small flat-head screwdriver (not supplied) is
needed to adjust the level.

Crossover: The amplifier has a built-in Butterworth crossover,
variable from 50 Hz to 250 Hz with a slope of 12dB/octave. It can be set to
high-pass, all-pass (full range), or low-pass operation. The rotary frequency
setting can be adjusted with a small screwdriver.

Punch EQ: The amplifier has an Punch EQ function that
changes with the crossover switch. When the crossover is set to low-pass, the
Punch EQ acts as a variable bass boost; 0 to +18 dB at 45 Hz. When the crossover
is set to high-pass, the Punch EQ acts as a variable treble boost, 0 to +14 dB
at 12.5 kHz. When the crossover is set to all-pass, both the bass and treble
boost circuits are active.

Connections

Power Connections: The TM400X2ad's power, ground, and remote
turn-on terminals are located on a single, removable plug. This allows you
quickly and easily connect or disconnect the amplifier. Each individual terminal
on the plug is a captive c-clamp connector which will accommodate up to 8-gauge wire. A Phillips-
or flat-head screwdriver (not supplied) is required
to tighten/loosen the terminals.

Fuse: The amplifier does not have an on-board fuse. A 60-amp fuse should be placed on the power wire within 18" of the battery.

Speaker Connections: The amplifier is equipped with a
speaker output harness, which connects to the amplifier via a 4-pin plug. The
speaker wires should be spliced to the 16-gauge bare wires on the 8" pigtail. To
bridge the amplifier, you should use the left positive (white) and right
negative (gray/black stripe) terminals.

Signal Input: The amplifier's Differential Inputs will
accept either a line-level or speaker-level input on the Molex-style connector.
The included input harness has a 4-pin Molex plug and dual RCAs. A line-level
signal can simply be connected via RCA cable from the source unit to the input
harness. For a speaker-level signal, you can cut the RCA connectors from the
input harness and splice the wires to the speaker wires of the source unit. When using a
speaker-level input signal, the auto turn-on feature is active and the remote
turn-on terminal becomes a 12 volt output, which can be used to turn on/off an additional amplifier
or other component.

Punch Level Control (PLC): An RJ-45 jack is provided for
connecting the optional
PLC2
Remote Punch Level Control (sold separately), allowing remote control of the output level of
the amplifier. The PLC2 conveniently mounts under the dash, inside the center
console, or in the glove box.

Optional Custom Mounting Kit: The optional
RFKHD9813 amplifier installation kit is designed for custom-mounting the
TM400X2ad to compatible Harley-Davidson motorcycles. The kit includes a mounting
plate, heatsink, and wiring kit. You may qualify for a One-Year Extended
Warranty when you install the TM400X2ad with a matching Rockford Fosgate
Amplifier Installation Kit.
